Research.My own research
is described here.
The main theme is
analysis of algorithms, most
notably in the areas of
computational number theory and information theory,
this with a strong component related to dynamical systems.See the pages of the Reseach Team
Algorithmics at Caen,
of the
Dynamic
Analysis of Algorithms Group, and the page
of a nationwide special interest group on
Dynamical
Systems and Modelling in Algorithmics
(which I have been coordinating together with Christiane Frougny and Jean Mairesse). I am also an associate member of the
Algorithms Project
at INRIA and an active member of the French
ALEA
working group. I have been a member of the Programme Committees of
the international workshops Analysis of Algorithms.
(we have organized the Tatihou
meeting in 2001.)

Administration.For the period 2000-2003, I have been director of the Research
Laboratory GREYC.
I currently have served as advisor for the
"STIC" department at CNRS,
being more specifically in charge of theoretical computer science
and relations between CS and Maths.
I am currently directr of a national research federation
called GDR IM (Ïnformatique mathématique"), which counts about 500 members.
